We all know Black Ops 2 is coming to a close very soon and all the map packs are already finished. Treyarch probably has the ideas for the next zombies maps and gamemodes for the next game, but they probably aren't done thinking about it. This is a great time to tell Treyarch what we want. Post your zombies map ideas with wonderweapons and new perks!
What I really think would be cool is something similar to Grief, only cooler. Four players, or Eight split into teams of two, have to find four specific parts around the map (there are four of each part, scattered in random places) and the first person/team to get all four parts back to their workbench and build 'The Beacon' can then climb to the top of the map and use it to be rescued and win. It could be called 'Race' or 'Escape'.
Also, as a pre-order bonus, Hijacked Zombies!
It wouldn't be done in rounds. There would be a timer (going up, not down) and the longer the game took, the more zombies would spawn and the tougher they'd be. But the trick is, players still have to buy doors and maneouver their way around the map, so they'd have to buy weapons to fight the zombies and try to buy your way through the whole map, find the parts and return, and every second is precious. Maybe it could be called 'Speed Run' instead.
Also, what do you think of Hijacked Zombies?
